This post doesn't help me at all. I Upgraded from a 750 GB Hard Disk to a Western Digital 2 TB Hard Disk. So, with that being said when I try to add more Music I get this Message: Friend if you want to add more Music you have to Delete some Songs! Is Microsoft creating this issue?
So, I just found out apparently it’s because of a contractual obligation thanks with all of the major labels. They don’t want you to be able to “own” such a large quantity of music through a streaming service.
